Quantum Hall charge sensor for single-donor nuclear spin detection in silicon
We propose a novel optical and electrical hybrid scheme for the measurement of nuclear spin qubits in silicon. By combining the environmental insensitivity of the integer quantum Hall effect with the optically distinguishable hyperfine states of phosphorus impurities in silicon, our system can offer both nuclear spin measurement and robustness against environmental defects. 31P donor spins in i...
متن کاملThe Quantum Hall Effect: Spin-Charge Locking
In two-dimensional electron gas when a large magnetic field is applied in one direction and an electric field perpendicular to it, there is a current in a direction perpendicular to both. This current is called the Hall effect. It remained without quantization until 1980 when it was found that the quantization leads to correct measurement of h/e .Therefore the quantized Hall effect was further ...
متن کامل0 Spin - Charge Separation and the Spin Quantum Hall Effect
We use quantum field theory methods to study the network model for the spin quantum hall transition. When the couplings are fine tuned in a certain way, the spin and charge degrees of freedom, corresponding to the supercurrent algebras su(2)0 and osp(2|2)−2 respectively, completely decouple. This simpler theory is exactly solvable and some critical exponents are computed and shown to agree with...
متن کاملQuasi - Spin - Charge Separation and the Spin Quantum Hall Effect
We use quantum field theory methods to study the network model for the spin quantum Hall transition. When the couplings are fine tuned in a certain way, the spin and charge degrees of freedom, corresponding to the supercurrent algebras su(2)0 and osp(2|2)−2 respectively, decouple in the renormalization group flow. The infrared fixed point of this simpler theory is the coset osp(4|4)1/su(2)0 whi...
متن کاملSilicon-based spin and charge quantum computation
Silicon-based quantum-computer architectures have attracted attention because of their promise for scalability and their potential for synergetically utilizing the available resources associated with the existing Si technology infrastructure. Electronic and nuclear spins of shallow donors (e.g. phosphorus) in Si are ideal candidates for qubits in such proposals due to the relatively long spin c...
